Abstract: Technology is described for steep angle of a focal track of an anode of an x-ray tube. In one example, an anode includes a disc-shaped anode and a focal track. The disc-shaped anode includes a bearing-facing surface, a window-facing surface positioned opposite the bearing-facing surface, and a focal track positioned between the window-facing surface and the bearing-facing surface, wherein the focal track is angled with respect to the window-facing surface, and the angle between the focal track and the window-facing surface is between 45° and 89°.

Abstract: Disclosed herein are a high-voltage generator for an x-ray source, an x-ray gun, an electron beam apparatus, a rotary vacuum seal, a target assembly for an x-ray source, a rotary x-ray emission target, and an x-ray source. These various aspects may separately and/or together enable the construction of an x-ray source which can operate at energies of up to 500 kV and beyond, which is suitable for use in commercial and research x-ray applications such as computerized tomography. In particular, the high-voltage generator includes a shield electrode electrically connected intermediate of a first voltage multiplier and a second voltage multiplier. The electron beam apparatus includes control photodetectors and photo emitters having a transparent conductive shield arranged therebetween. The rotary vacuum seal includes a pumpable chamber at a position intermediate between high-pressure and low-pressure ends of a bore for a rotating shaft. The rotary target assembly is configured such that when a torque between a bearing housing and a vacuum housing exceeds a predetermined torque, the bearing housing rotates relative to the vacuum housing. The rotary x-ray emission target has a plurality of target plates supported on a hub, the plates being arranged on the hub to provide an annular target region about an axis rotation of the hub. The x-ray gun is provided with a shield electrode maintained at a potential difference relative to the x-ray target different to the electron beam emission cathode.

Abstract: X-ray sources and production of X-rays, in particular, producing monochromatic x-rays is provided. More specifically, a method for producing X-rays and the use of the X-ray source for x-raying bodies (for example human bodies). An aerogel, for example in the form of a rod, may be provided in a housing as a target. Said target may be bombarded with an electron beam, the aerogel being vaporized due to the extreme low density and the high energy. As a result, the target is guided by means of a roller such that an unused target for producing, in particular, the monochromatic X-rays, is always available.

Abstract: A system and method for x-ray tube components is disclosed. The method of fabricating an x-ray tube component includes providing a powder into an electrically conductive die constructed to have a cavity shaped as the x-ray tube component being fabricated and simultaneously applying a mechanical pressure and an electric field to the die so as to cause sintering of the powder and thereby fabricate the x-ray tube component, wherein the electric field applied to the die directly passes through the die to the powder, so as to generate heat internally within the powder responsive to the applied electric field.

Abstract: Described is an X-ray rotating anode plate having a base and X-ray active layer having the described acceptable properties and a method for producing same. The base comprises carbon nanoparticles in quasi-homogeneous spatial distribution. Carbon nanoparticles can be selected from among carbon nanotubes, nano-graphite powder particles having a substantially spherical shape, and mixtures thereof. The inclusion of described additives improves the stability and heat conductivity of the base. With the described method, the starting materials for the base and X-ray active layer, and other optional materials which may form functional layer are compressed to a preselected shape in a pressing mold with simultaneous application of pressure, elevated temperature and varied electric currents, compressing the shape to a final density exhibiting high-strength diffusion bonds between these starting materials. The described X-ray rotating anode plate can be used, for example, in high-performance X-ray tubes for X-ray computer tomography.

Abstract: An apparatus and method for applying an absorptive coating to a portion of the evacuated enclosure in an x-ray generating device is disclosed. The absorptive coating is applied to the inner surface of the evacuated enclosure to enhance its heat dissipation characteristics, which in turn assists in tube cooling during x-ray production. The absorptive coating is applied atop an intermediate bonding layer. Both the absorptive coating and the intermediate bonding layer are applied to the evacuated enclosure surface by electroplating processes. A plating apparatus comprising the evacuated enclosure portion, a plating fixture, and a base plate is used both to contain the electroplating solution during the plating process, as well as to facilitate its entry into and removal from the evacuated enclosure. A method of employing the plating apparatus to apply the intermediate bonding layer and the absorptive coating is also disclosed.
